iMPaovEMENT iN Frown-PACKERS.

Specification forming part of Letters Patent No. 432,463, dated April 26, 1864.

To all whom it may concern:

Be it known that I, ISAAC COOK, of St. Louis, in the county of St. Louis and State of Missouri, have invented a new and Improved Flour-Packer; and I do hereby declare that the following isa full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this` specineation. in which- Figure 1 represents a. sectional front elevation of my invention. Fig. 2 is a side eleva` tion ofthe same. Y

Similar letters of reference in both views indicate corresponding parts.

This invention consists in a Hour-packer the spout of which is made of wood and provided atits bottom end with an auger-chamber and auger rotating on a vertical shaft, in combination with a rising and-falling barrelplatform which is forced up by a wei ght, and the sraiu exerted by this weight on the platform is regulated according to the increasing quantity of flour in the barrel by means ot' a sliding weight and friction-brake in such a manner that the flour throughout the whole barrel is compressed with uniform density by the automatic action ofthe packer. y

The invention consists a so in a tappet at.- tached to one-of tl e upright guidcbars of the barrel-plati'orn'l in combina tion with a hooked red connecting with a weighted lever, which is pivoted to the sliding journal-box of the main drivingshaft in such a manner that as soon as the platform has descended to its lowest point the tappet strikes the end of the rod and throws the drivingslial't out of gear with the auger-shaft.

To enable others skilled in the art to make l and use my invention, I will proceed to describe it.

A represents a frame, made of wood or any other suitable inaterial, and provided with two grooved uprights, a, which form the guides forthe risingandfalling platform B. This platform is suspended from two ropes or chains, b, which are secured to the standard c,'rising from its middle, one on cach side, and said standards are steadicd by braces d, so lthat the platform is evenly supported in the,

The ropes b, 'from which the platform B is suspended, ,are connected to the peripheries of rollers c, which are rmlykeyed to ahorii zontal shaft, G. Thisshaft hasits bearings in the uprights a of the frame A, and it extends through said uprights on both ends. One end bears the drum I), and a rope, f, which is fastened at one end to the periphery of this drum and wound round it several times, extends from the same over a pulley, g, and supports the weight F. This weight moves up and down in a box, E, extending throughout the full height ot' the frame A, or nearly so, and it must ber sufficiently heavy to counteract the weight of the platform B with the barrel, and to exert beside an upward strain on said platform of such a power as may be required.

to raise the platform and 'barrel up to the au ger ready for packing.

In order to `compensate for theinereasing wei ght ofthe barrel as the same lls with Hour,

and to produce the desired pressure for packing, a pulley, G, is secured to 'that end of the shaft C opposite the drum D, and to the center of this drum a pinion, h,isrmly fastened.

This pinion gears into a toothed segment, t', y

which oscillates on a pivot-7, inserted in the outside of one of the uprigiits a, and it connects by a rod, k, with a carriage, l, from which a weight, m, is suspended, as clearly shown in Fig. 2 of the drawings.

The carriage I, which supports the weight l m, slides in and out on a lever, H, which is v pivoted to the outside of one of the uprights a., under thepulley G, and which is connected to the end of a strap, n, that entends round an arc of one hundred and eighty degrees (more or less) of the pulley G iu such a manner that by depressing the front end ofthe lever said strap is drawn up tight against the periphery of the pulley and acts as a brake. The force with which this brake is applied naturally depends upon the power with which the front end of the lever H is depressed, and said force increases if the carriage and the weight m are moved toward the outer end of said lever, and by moving them in the opposite direction the force with which the brake is applied decreases.

At the beginning of the operation the platform, with the barrel, is raisedto its highest point, and the segmenti and carriage l are in theposition shown in red outlines in Fig. 2. As the barrellls the platform descends and the pulley Gr turns in the direction of the arrow marked on it in the same ligure, and the seg.

ment moves in the direction of the arrow marked thereon. By these means the carringe L is gradually moved .toward the outer end ofthe lever Hand the force with which the brake is applied increases until the platform'has reachedits lowest point. The mo-.iJ tion ofthe carriage l is regulated by moving the pin which connects the rod k with the toothed segment z' .nearer to or farther from the pivot j., on which said segment oscillate's, and it will be readily nnderstoodthat by increasing lthe distance between said pin and pivot the motion ofthe carriage Z is increased,

, and vice versa.

Theiouris introduced in the bar-rel through a spout, I, which is secured in the middle of its bearings above in a cross-bar, o, secured between the uprights a` ofthe frame A, and

below at a short distance from the anger in a cross-bar, p, that is fastened to the lewer ed ge of thewooden part of the spout. A,

A bevel-wheel, g, is mounted on'the upper' end of the a-rbor L, and said arbor receives a rotary motion by another bevel-wheel,` r, which is secured `to the driving-shaft M. That 'end of this shaft next to therbevellwheel r has its bearingin a box, a, to which a vertically',- sliding motion can be'-imparted, and by moving said box up thel bevel wheel ris thrown out of gear with the wheel q, and' the 'motion of thejarbor L stops, and bymovgingthe box down the wheel 'r-'is' thrown in gear'with the wheel lq andthe'arbor-jL rotates. (This 4slid"- ing motion ofthe.' box stis eitect'edfantom at'-v -..ically by eleven-Nt whehis pirated tn :its

outside, and which has its fulcrum on a. projection, t, bearing on the cross'bar o. A. weight, 0, suspended from its rear end, forces the box s up, and a rod', P, which is connected to its front end, serves to pull siaid front end together with the box down and to throw the bevel-wheels q1 'r in `gear with each other. This rod extends down to lthe lower part of the frame A, and its lowerend is bent so that it can be made to catch over a stop, u, secured to one of the uprights a.. if the rod is pulled down so that it hooks over the stop u, its lower end is in such a position that a iappet, lv,` secured to the front side of oneof the standards von the platform B, will strike the same whenever said platform descends low enough, and by the action ot' said 'tappetil the rod is caused to release the stop u, and the weight O causes 'the rear end of the lever N- to descend, and the box s is raised. By this arrangement the motion ot' the auger is stopl ped automatically as soon as the barrel' has.

been illed up, and a waste of Hour is avoided. The tappet c is adjustable up, and downfso that it can be set to correspond to the height ot' different barrels. A flour-packer can thus lbe constructed which is very compact, cheap, and reliablefin its operation.

What I claim as new, and desire to secnre` The weighted lever N, hooked rod P, v stop'u, in combination with the tappetf ni the platform B, andwith the sliding boteC :the driving-shaft, constructed and operating in themanner and. for the" purpose substantiallyas set forth.

' Isaac soon.
